[0007] Against this background, the task was to present the display content of a vehicle in a suitable manner to an occupant.

[0008] This problem is solved by a display system and a method with the features of the independent claims. Embodiments of the display system and the method are described in the dependent claims and the description.

[0009] The display system according to the invention is designed for a vehicle, e.g. a motor vehicle, and has a rectangular display field or display with four outer edges and at least two mirror modules. A reflection chamber of a frame for the display field is arranged at at least two of the outer edges of the display field that are arranged parallel to each other, with the display field being arranged between the two parallel reflection chambers.

[0010] The display field has a front side (front base) and a back side (rear base), with a display area integrated into the front side for showing the respective display content. In the presented embodiment of the display system, each of the at least two parallel reflection spaces has a front side (front base) and a back side (rear base). All front sides face an observer, such as an occupant of the vehicle, and are visible, while all back sides are concealed.

[0011] Furthermore, each reflection chamber, usually cuboid in shape, has an inside and an outside, with the inside facing an outer edge of the display field and the outside facing away from it. The inside of each reflection chamber is at least partially bounded by a wall forming an outer edge of the display field, and an outside of each reflection chamber is bounded by another wall.

[0012] In the display system, the front sides of the parallel reflection chambers are covered and / or limited by at least one front mirror module and the rear sides of the parallel reflection chambers by at least one rear mirror module, wherein light sources are arranged on at least one of the two walls on the inside and / or outside of each reflection chamber, wherein the light sources for each reflection chamber are arranged along at least one line in a band and / or a strip and are designed to emit light into the respective reflection chamber, wherein the two mirror modules are designed to reflect the light in the respective reflection chamber mutually and / or reciprocally by providing an endless mirror and / or mirror hole effect, i.e., to reflect back and forth in the reflection chamber between the mirror modules.The resulting reflections of light are visible through the at least one mirror module arranged on the front sides and are designed to create an optical depth effect between the reflection spaces for the display field and the viewer of the same.

[0013] From the viewer's perspective, reflections of the light elements or light sources are visible from each reflection chamber, which forms part of the frame for the display field. These reflections optically form a line, for example, a continuous line, with this line running parallel to the respective outer edge of the display field on which the reflection chamber is located. The width of each line, which is displayed to the viewer by a respective mirror module on the front of the reflection chamber, is greater (thicker) the further the line is from the outer edge of the display field, and smaller (thinner) the closer it is to the outer edge. The elements arranged along the line and / or strip parallel to the outer edge...Surrounding light elements can be controlled and / or regulated separately and their color and / or brightness can be varied optionally, whereby both the brightness and the color can be changed.

[0014] Typically, a horizontally oriented reflection chamber is arranged at each of the two horizontal outer edges of the display field, or possibly only at the two horizontal outer edges. Alternatively or additionally, a vertically oriented reflection chamber is arranged at each of the two vertical outer edges of the display field, or possibly only at the two vertical outer edges.

[0015] If the display system has four reflection chambers (two vertically and two horizontally oriented) arranged at all four outer edges of the display field, the at least one mirror module, which covers the front faces of all reflection chambers, displays several nested rectangles. These rectangles are formed by the light elements arranged along the lines and their reflections, optically forming multiple frames. Each side of each rectangular frame is formed by a line of light elements emitted from a single reflection chamber. The largest frame has the thickest lines, and the smallest frame has the thinnest lines.

[0016] The at least one front mirror module, which covers the front of a respective reflection chamber, is designed and / or designated as a partial mirror that reflects only a portion of the light propagating specularly between the two mirror modules back into the reflection chamber, e.g., a first fraction of x%, and transmits or allows a second fraction of 100% - x% to the outside, thereby indicating the individual lines. This mirror module is partially reflective and partially transparent, e.g., semi-reflective and semi-transparent if x = 50.

[0017] The respective front mirror module consists of a transparent sheet of glass or plastic, e.g., Plexiglas, wherein one side of the mirror module facing the reflection chamber has a layer and / or film that is only partially reflective, according to a fraction of x%, and / or is coated with such a layer or film. The at least one rear mirror module, which covers the back of the respective reflection chamber, is designed and / or designated as a full mirror that completely reflects light that propagates specularly between the two mirror modules into the reflection chamber. Each front mirror module can be designed and / or designated as either a partially transparent, e.g., semi-transparent, and partially reflective, e.g., semi-reflective, front cover or as a completely reflective rear cover or surface of the respective reflection chamber.

[0018] Furthermore, at least one base surface, i.e., the front and / or the back, of at least two parallel reflection chambers, usually all reflection chambers, is covered by its own mirror module. In the case of four reflection chambers, the four mirror modules for the respective front and / or back base surfaces are connected and / or linked together, forming a continuous and / or one-piece frame-shaped mirror module that covers the front and / or back surfaces of all reflection chambers. The mirror modules can form a one-piece frame-shaped cover with a cutout in the area of ​​the front or back of the display field. Alternatively, the mirror modules and a transparent window for the display field can form a continuous rectangular cover in the area of ​​the front of the display field, with the semi-transparent orThe partially reflective mirror modules enclose and / or frame the window located between them.

[0019] It is also possible that the rear sides of all reflection spaces and also the enclosed rear side of the display field are covered by a common rectangular one-piece mirror module.

[0020] In a further embodiment, the display system has at least one actuator motor designed to pivot and / or rotate the at least one rear mirror module vertically and / or horizontally relative to the display surface on the front of the display field, depending on a rotation and / or direction of rotation as a movement of the vehicle around at least one spatial axis, which is detected by at least one sensor of the display system and / or the vehicle in a respective driving situation, i.e., each a separate rear mirror module to cover one rear side of a reflection space or a single rear mirror module to cover the rear sides of all reflection spaces and the display field.The at least one actuator, depending on a signal provided to it by the at least one sensor regarding the currently detected movement, is configured to rotate the at least one rear mirror module about the at least one vertical axis in the direction of rotation opposite to the sensor-detected direction of rotation of the vehicle, whereby the movement, i.e., at least the rotation, of the vehicle is optically compensated by an opposing movement, e.g., rotation, of the at least one rear mirror module. In this embodiment, the at least one rear mirror module is rigidly arranged and parallel to the display area of ​​the display field. Furthermore, the at least one front mirror module is rigidly arranged and parallel to a display area of ​​the display field.Alternatively or additionally, it is also possible that the at least one rear mirror module is to be rotated with respect to the at least one vertical axis in the same direction of rotation as the sensor-detected direction of rotation of the vehicle.

[0021] The light sources, for example, designed as light-emitting diodes (LEDs), are arranged on and / or in the wall that covers and / or delimits the inside of a respective reflection chamber, or on and / or in the wall that covers and / or delimits the outside of a respective reflection chamber. The wall for the inside can simultaneously serve as the outer edge of the display module. In one embodiment, the display system can have a housing and / or be arranged in a component of the vehicle, wherein the housing and / or component has a recess in which the display field and the reflection chambers are arranged. An inner wall of the recess can simultaneously serve as the wall that covers and / or delimits the outside of a respective reflection chamber.

[0022] The method according to the invention is designed for operating a display system, for example, an embodiment of the display system described above, for a vehicle. The display system has a rectangular display field with four outer edges and at least two mirror modules, wherein a reflection chamber of a frame is arranged at at least two mutually parallel outer edges of the display field, with each parallel reflection chamber enclosing the display field located between them. The front sides, as the front base sides of the two parallel reflection chambers, are covered and / or limited by at least one front mirror module, and the rear sides, as the rear base sides of the two parallel reflection chambers, are covered and / or limited by at least one rear mirror module.In this arrangement, an inner side of each reflection chamber is at least partially bounded by a wall designed as the outer edge of the display field, and an outer side of each reflection chamber is bounded by another wall, wherein light sources are arranged on at least one of the two walls of each reflection chamber, wherein light is emitted from the light sources into the respective reflection chamber, wherein the light is reflected mutually and / or alternately by the two mirror modules in the respective reflection chamber by providing an endless mirror and / or mirror hole effect, wherein reflections of the light through the at least one mirror module arranged on the front sides become or are visible and create an optical depth effect for the display field between the reflection chambers.

[0023] The method is performed for a vehicle display system and / or in a vehicle for which a vertical axis, usually oriented vertically, a transverse axis, and a longitudinal axis, both usually oriented horizontally, are defined and / or are defined as spatial axes, wherein a rotation and / or direction of rotation is detected as a movement of the vehicle about the at least one spatial axis by at least one sensor of the display system and / or the vehicle, which is designed to detect this movement. The vehicle rotates about its vertical axis when cornering to the left or right.

[0024] Furthermore, at least one rear mirror module is rotated relative to a display area of ​​the display field, in the opposite direction to the sensor-detected rotation of the vehicle. During travel, the vehicle rotates around a spatial axis parallel to two reflection chambers, with the at least one rear mirror module for each of these two reflection chambers rotating relative to a display area of ​​the display field, in the opposite direction to the sensor-detected rotation of the vehicle. Additionally, it is possible for a first color to be emitted into the respective reflection chamber by the light sources of one of the two reflection chambers, and a second color to be emitted by the light sources of a second reflection chamber.

[0025] In this embodiment, the at least one sensor determines a roll angle during a rotation about a roll axis of the vehicle corresponding to its longitudinal axis, a pitch angle during a rotation about a pitch axis of the vehicle corresponding to its transverse axis, and / or a yaw angle during a rotation about a roll axis of the vehicle corresponding to its vertical axis, and the at least one rear mirror module is rotated opposite to the respective detected angle.

[0026] It is possible that the vehicle, for example due to a steering maneuver, is moved laterally to the left or to the right, e.g., steered or driven, whereby in the case of a movement to the left, the vehicle is rotated counterclockwise to the left around the vertical axis, or in the case of a movement to the right, clockwise to the right, whereby each lateral movement, e.g., rotation, of the vehicle is detected by sensors in the respective lateral direction or according to the respective direction of rotation, and the at least one rear mirror module is rotated relative to the display surface in the opposite direction to the lateral movement, e.g., rotation.

[0027] Reflection chambers can be used to create a light frame for the vehicle's display area to combat motion sickness, provided the resulting mirror-hole effect is rotated in the opposite direction to a sensor-detected direction of rotation. This method reduces motion sickness experienced by a viewer of the framed display area by adjusting the mirror-hole effect generated by the reflection chambers, typically depending on the direction of rotation, if the viewer is peripherally aware of the vehicle's movement. The frame formed by the reflection chambers, for example, a light frame, can also create a depth effect for the enclosed display area, contributing to an immersive perception. The mirror-hole effect and / or continuous mirror effect create a comprehensive perception for the viewer, thus effectively reducing motion sickness.

[0028] Furthermore, the display content shown by the display field, which is known and / or determined, is also taken into account, with adjustments made to the mirror hole effect and / or the respective direction of rotation of the at least one mirror module. Thus, the design differs for moving and / or dynamic images, such as films, as display content compared to static images, which are, for example, read. For both static and dynamic display content, such as an image or multiple images, the reflection space with the light sources (LEDs) is adjusted to the color and brightness of an outer area and / or edge of the display content. If the vehicle's movement changes, the reflection space can be illuminated more brightly when the vehicle accelerates, or dimmed when it accelerates or decelerates.Accordingly, the lighting of the reflection space can be adapted to changes in the movements of dynamic display content, e.g., a film, thereby increasing immersion.

[0029] To reduce motion sickness, the vehicle's driving dynamics are visually represented by the display system, whereby at least one mirror module is rotated against a sensor-detected direction, e.g., direction of rotation, and / or optionally in the sensor-detected direction, e.g., direction of rotation. With two parallel, vertically or horizontally oriented reflection chambers, the spatial axis to be considered can run parallel between the reflection chambers. The reflection chamber located on the side of the intervening spatial axis from which the vehicle moves away during a rotation around the respective spatial axis is visually emphasized compared to the other parallel reflection chamber. The other reflection chamber is visually reduced.In this design, the brightness of the light sources in the reflection chamber to be visually emphasized is increased, while the brightness of the light sources in the other reflection chamber is reduced. This enhances the depth effect for the reflection chamber whose light sources are set brighter than those in the other.

[0030] When driving through a right-hand curve, the light from the designated light sources is increased or made brighter for a reflection chamber located to the left of the display, while the light from the light sources for a reflection chamber located to the right of the display is reduced. Conversely, when driving through a left-hand curve, the light from the designated light sources is increased or made brighter for a reflection chamber located to the right of the display, while the light from the light sources for a reflection chamber located to the left of the display is reduced.

[0031] The mirror-hole effect can also be enhanced by selecting the colors of the light sources. For the reflection chamber that is to be visually emphasized, a bright and / or vivid color, such as red or light green, is selected, while for the other reflection chamber, a comparatively muted and / or dark color, such as dark blue or gray, is selected.

[0032] The same phenomenon occurs during acceleration, usually positive, of the vehicle, during which it rotates clockwise around its transverse axis, or during braking, which is negative acceleration and also rotates clockwise around its transverse axis. During acceleration, when the vehicle is rotated upwards by a pitch angle, the lower of the two horizontally arranged reflection spaces is optically emphasized and the upper one is optically reduced, contrary to the direction of rotation. Conversely, during braking, when the vehicle is rotated downwards by a pitch angle, the upper of the two horizontally arranged reflection spaces is optically emphasized and the lower one is optically reduced, contrary to the direction of rotation.

[0033] It is possible to combine the individually adjustable optical highlights of the reflection spaces, i.e., the horizontal reflection spaces when accelerating or braking and / or the vertical reflection spaces when driving through a curve.

[0034] Furthermore, the display system can be used to provide an entertainment function. Here, the displayed content on the screen can be enhanced by adjusting the color and / or brightness of the light sources, which are, for example, LEDs. The colors of displayed images and / or the distribution of colors within a given image can be visually expanded by adjusting the colors in the reflection chambers, and the display area of ​​the screen can be visually extended to include the frame formed by these reflection chambers. For example, if a film is being watched in a scene depicting a beach with the sea, the light sources in the upper reflection chamber would be set to blue and the light sources in the lower reflection chamber to yellow. To visually emphasize music, the light sources can be synchronized to the beat of the music.A function and / or mode for colored and / or asymmetrical illumination of the reflection spaces can be activated by a vehicle occupant or automatically. Possible modes include an "Anti-Motion Sickness" mode, a "Movie Support" mode, a "Music Frame" mode, and / or an "Ambient" mode, for example, when the display system is networked with ambient lighting.

[0035] It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or on their own, without leaving the scope of the present invention.

[0036] The invention is schematically illustrated with reference to embodiments in the drawing and is described schematically and in detail with reference to the drawing. Fig. Figure 1 shows a schematic representation of a first embodiment of the display system according to the invention for carrying out a first embodiment of the method according to the invention. Fig. Figure 2 shows a schematic representation of a second embodiment of the display system according to the invention for carrying out a second embodiment of the method according to the invention.

[0037] The figures are described in a coherent and comprehensive manner. The same reference symbols are assigned to the same components.

[0038] The in Fig. 1 The first embodiment of the display system according to the invention, shown schematically in sectional view, for a vehicle designed here as a motor vehicle, is arranged in a recess in a component 2, here a cockpit structure, in an interior of the vehicle.

[0039] The display system has a central display field 4, which is framed and / or surrounded by four reflection spaces 6a, 6b, wherein in Fig. Figure 1 indicates only an upper horizontally arranged reflection chamber 6a and a lower horizontally arranged reflection chamber 6b. The display system also has a left vertically arranged reflection chamber and a right vertically oriented reflection chamber parallel to it. Each reflection chamber 6a, 6b has an inside, an outside, a front base designed as the front, and a rear base designed as the back.Furthermore, for each reflection chamber 6a, 6b, its inner side is provided by a wall forming the outer edge of the display field 4, its outer side by a wall forming the inner wall of the recess of component 2, its rear side by a mirror module formed as a full mirror 8a, 8b, and its front side by a mirror module formed as a half mirror 10a, 10b, wherein the outer edge, the inner wall of the recess of component 2, and the two mirror modules enclose each reflection chamber 6a, 6b. Additionally, light-emitting diodes are arranged as light sources 12 in and / or on the inner wall of component 2 along a strip and / or a line. A surface of the full mirror 8a, 8b on the rear side of the reflection chamber 6a, 6b, facing the reflection chamber 6a, 6b, is completely mirrored and / or 100% reflective.In contrast, a surface of the half-mirror 10a, 10b on the front of the reflection chamber 6a, 6b, which faces the reflection chamber 6a, 6b, is only partially mirrored, here half-mirrored and / or reflects 50% of light and is also 50% transparent to light.

[0040] In the first embodiment of the inventive method for operating the first embodiment of the display system, light from the light sources 12 is emitted into the respective reflection chambers 6a, 6b, wherein the light is reflected back and forth between the two mirror modules and / or between the two mirror modules in the respective reflection chambers 6a, 6b by providing an endless mirror and / or mirror hole effect. Reflections of the light by the at least one partially mirrored mirror module or the half-mirror 10a, 10b arranged on the front, which is partially transparent to light from the reflection chambers 6a, 6b (here 50% transparent or half-transparent), become visible to an observer 16 inside, whereby reflections of the light from a fully mirrored mirror module designed as a full mirror 8a, 8b by the half-mirror 10a, 10b are also visible. This is done for the display field 4 or...For a displayed content between the reflection spaces 6a, 6b, an optical depth effect visible to the viewer 16 is created.

[0041] The in Fig. 2 The second embodiment of the display system according to the invention, shown schematically in sectional view, is also arranged in a recess of a component 32, here a cockpit structure, in an interior of a vehicle.

[0042] The display system has a central display field 34, which is framed and / or surrounded here by four reflection spaces 36a, 36b, wherein in Fig. 2 Only an upper horizontally arranged reflection chamber 36a and a lower horizontally arranged reflection chamber 36b are indicated. The display system also has a left vertically arranged reflection chamber and a right vertically oriented reflection chamber parallel to it, each reflection chamber 36a, 36b having an inside, an outside, a front, and a back, its inside being covered and / or bounded by an outer edge of the display field 34, its outside by an inner wall of the recess of component 32, and its front by a mirror module designed as a half-mirror 40a, 40b. All four partially light-transmitting mirror modules designed as half-mirrors 40a, 40b enclose a largely completely light-transmitting transparent window 39, which covers one front of the central display field 34, in a frame-like manner.The partially translucent mirror modules on the reflection chambers 36a, 36b and the window 39 on the display field 34 form a single, continuous front cover 37 of the second embodiment of the display system. This cover 37 comprises a light-transparent layer, e.g., a disc or a film, wherein those sections of an inner surface of this layer that face and cover a respective reflection chamber 36a, 36b are partially mirrored, here semi-mirrored, and / or 50% reflective and 50% transparent.

[0043] As an alternative to the first embodiment from Fig. 1 The rear sides of the reflection chambers 36a, 36b and also a rear side of the display field 34 framed by them are covered by a single, one-piece, continuous solid mirror 38 as a fully mirrored mirror module for all reflection chambers 36a, 36b. The display system includes an actuator 48, which is arranged in the recess of the component 32, connected to the solid mirror 38 and is designed to tilt the solid mirror 38 horizontally, i.e., to the left or to the right, and / or to rotate it about the vertical axis relative to the reflection chambers 36a, 36b about a vertically oriented vertical axis of the vehicle and / or the display field 34. The actuator 48 is further configured to tilt the full mirror 38 relative to the reflection spaces 36a, 36b vertically, i.e. downwards or upwards, and / or to rotate it around the transverse axis about a horizontally oriented transverse axis of the vehicle and / or the display field 34, which is described here in Fig.Figure 2 explicitly shows this schematically. The distance between the full mirror 38 and a respective half-mirror 40a, 40b on the front face of a respective reflection chamber 36a, 36b is changed, as is the size and / or extent of the respective reflection chamber 36a, 36b. In the reflection chamber 36a, 36b where the front half-mirror 40a, 40b is closer to the full mirror 38, the depth effect is reduced. Conversely, in the reflection chamber 36a, 36b where the front half-mirror 40a, 40b is further away from the full mirror 38, the depth effect is increased.

[0044] In the second embodiment of the inventive method for operating the second embodiment of the display system, light from the light sources 42 is emitted into the respective reflection chambers 36a, 36b and further reflected in each reflection chamber 36a, 36b by the half-mirror 40a, 40b, using a continuous mirror and / or mirror hole effect, and totally reflected by the common full mirror 38. Reflections from the light sources 42 are visible to an observer 46 inside, creating a visible optical depth effect for the observer 46.

[0045] By rotating the full mirror 38 horizontally and / or vertically around its vertical axis and / or horizontal axis, an asymmetrical mirror hole effect and / or depth effect can be generated. The rotation of the full mirror 38 is adapted to a sensor-detected movement, in this case rotation, of the vehicle around its vertical and / or transverse axis during travel. The actuator 48 moves the rear full mirror 38 via a mechanism and / or a swashplate.

[0046] If the vehicle rotates around its vertical axis while driving through a curve, i.e., clockwise or counterclockwise (left or right), the solid mirror 38 is moved or rotated in the opposite direction around the vertical axis to optically compensate for the respective movement for the viewer 46. Alternatively or additionally, if the vehicle accelerates or decelerates, it rotates or rotates around its transverse axis, i.e., clockwise or counterclockwise (upward or downward), with the solid mirror 38 being moved or rotated in the opposite direction around the transverse axis to optically compensate for the respective movement for the viewer 46. This can reduce motion sickness for the viewer 46 of the display field 34.
